The observation of an adamantinoma's case propped up an odontogenic cyst to check the complicated histogenic problem connected to this eventuality. After considering several theories they suppose a probable derivation from the odontogenic epithelium that has undoubted potentiality.

Ameloblastoma is one of the most common benign odontogenic tumors of the jaw that constitutes about 10% of all tumors that arise in the mandible and maxilla. It is a slow-growing but locally invasive tumor that presents with painless swelling of the mandible or maxilla. The World Health Organization (WHO) classification of 2017 describes ameloblastomas of the following four types: ameloblastoma; unicystic ameloblastoma; extraosseous/peripheral ameloblastoma; and metastasizing ameloblastoma.

Diagnosis of odontogenic tumors can be challenging due to their rarity and diverse morphology, but when arising near the tooth, the diagnosis could be suspected. When their location is not typical, like inside the paranasal sinuses, the diagnosis is less easy. Maxillary ameloblastomas are exceedingly rare with only sparse information on their epidemiological, histological and genetic characteristics.

We present a case of a patient mainly complaining about obstruction on the right nasal cavity. Endoscopy and computed tomography revealed a soft tissue mass occupying the maxillary sinus to the middle meatus causing complete obstruction of the right nasal cavity.

Ameloblastoma or adamantinoma is the rarest of the three forms of tumor of the odontogenic type. They are benign, locally aggressive neoplasms arising from ameloblasts, which typically occur at the angle of the mandible, and are often associated with an un-erupted tooth and must, therefore, be differentiated from a dentigerous cyst which will be centered on the crown. When in the maxilla (less common), they are located in the premolar region, and can extend up in the maxillary sinus.

Ameloblastoma or adamantinoma is a benign odontogenic tumour arising in facial bones mostly in mandible. There are different modalities of treatment for ameloblastoma viz. chemotherapy, radiation therapy, curettage and liquid nitrogen but surgical resection or enucleation remains the most definitive treatment for this condition.
